Abstract: Recently, various content sharing methods that are available on peer-to-peer (P2P) networks, have been actively researched; a P2P network generally consists of a number of peers and evenly connected to each other. In most of previous studies, shared content items are supposed to be kept only in the storages of the peers, and effective ways of content sharing under the environment where not only the storages of peers, but also ones of a cloud system are available have not sufficiently researched yet. In this paper, we propose an efficient content sharing method in which an appropriate content acquisition rate can be set preliminarily according to the payable storage cost, and actually the rate can be maintained by keeping sufficient number of content replicas under the environment where storages of both peers and a cloud system are available.

Keywords: hybrid peer-to-peer; content sharing; cloud storage.
